I came across a troublesome file. How to make a sample to send for testing?
A sample is made by cutting a small piece from the original troublesome file. There are 2 ways (plus 1 more for HD DVD EVO files only) to make a sample. The first way is to use a hex editor (like the free HxD one). The second is to use drmpeg’s command line tools. The 3rd way, which applies only to EVO files, is more complicated: Load the troublesome file to Pelican9’s EVOdemux, press rebuild (select only the streams you want) and cancel the process after a while.
